Safety Instructions
1. All operators must be familiar with the stirrer and should read this entire
manual.
 2. Thestirrermustbesecurelyxedtoastablesupport.MounttoaCaframoStand
(Part Number A110) with a Caframo heavy duty clamp (Part Number A120). If
other stands or clamps are used, the unit must be secure and can not fall if tipped
up to ten degrees from the vertical.
3. The stirrer must be supplied with the rated voltage. See serial plate.
 4. CAUTION: Thisisnot anexplosionproof stirrer.Do notusewithhighly
ammableorexplosivematerials.
5. Spinning paddles or impellers can cause severe personal injuries. Operators
mustuseextremecareandgoodjudgementwhenmixingatanyspeed.The
BDC stirrers have higher torque capabilities than conventional stirrers.
 6. Allmixingpaddlesandimpellersmustbeingoodconditionwithstraightshafts.
If the stirrer vibrates at high speeds check the paddle shaft for damage and repair
or replace it.
 7. Extremecaremustbetakenwhenmixingchemicalssothatnochemicalsare
splashedoutsidethemixingvessel.Caremustbetakenwhenchangingtofaster
mixingspeeds.Onpowerup,theunitwilldisplayitssetspeedandwillclimb
to that speed when the pause button is pushed. Always start at lowest speed if
unsureofmaximumsafespeed.
 8. Ensurethatthemixingimpellerdoesnotcontactthecontainingvessel.
9. Do not operate while standing in water. Keep the unit dry and do not immerse
anypart,exceptthemixingpaddle,intoanyliquids.Protectfromsplashing.
10. Ensure that no loose clothing, jewelry, or hair can become entangled in any
rotating parts. Fast spinning chuck can cause injury to operator. Use chuck
guard provided when stirrer is in use.
11. Power can be interrupted to the stirrer by pressing the power button or by
disconnecting the mains cord. If rotating, this will cause the stirrer to stop and
will disconnect power to the stirrer’s internal drive circuit.
12. Shaft rotation can also be stopped by pressing the pause button. This does not
disconnect power to the stirrers internal drive circuit.
13. Wear safety goggles and suitable clothing when operating the stirrer.
14. Repairs must be carried out only by technicians authorized by Caframo.

Description
AllCaframostirrersarespecicallydesignedforprofessionaluseinthelaboratoryandfor
use in industry to stir numerous liquids with various properties and applications. The BDC
seriesofstirrersareavailableinsixdifferentmodels.
BDC1850
BDC1850-220 rotatesat12-1800rpmwithamaximumtorqueof568Ncm(50in-lbs)
BDC3030
BDC3030-220 rotatesat20-3000rpmwithamaximumtorqueof341Ncm(30in-lbs)
BDC6015
BDC6015-220 rotatesat40-6000rpmwithamaximumtorqueof170Ncm(15in-lbs)
*The “220” models operate on 220-240 volt mains voltage.
TheBDCstirrersuseadigitallycontrolledhighefciencybrushlessDCmotorwhichyields
high torque over a very wide speed range. The speed is kept constant with continuous
feedback to the motor. The BDC stirrers are designed for reliability and durability. There
are no wear parts that require user service during the normal life of the instrument. There
are no user serviceable parts.
The BDC stirrers incorporate smart logic for automatic transmission control. This logic
determines the appropriate speed range at which the stirrer should operate. See graphs on
page 8. The automatic selection can be overridden by pressing the stirrer range button.
With higher solution viscosities, more torque is required to stir at the same speed. When
the torque demands are outside the instrument’s range, the control logic slows down the
stirrer until the torque comes within the instrument’s range. If the torque demand is too
great at the stirrer’s lowest possible speed, the unit will automatically shut down.
The BDC stirrers are designed for safety. The unit comes on in “pause” mode once power
is activated. After a power interruption the stirrer remains off. The stirrer’s speed will
gradually ramp up to the desired set point after the pause button is pressed.
All BDC stirrers have integrated electronic overload protection which ensures no damage
can occur to the electronics, motor or transmission when an overload situation occurs, such
as too great a torque demand or unit overheating.
A chuck guard is supplied to place over the chuck. It protects the user from the spinning
chuck and also helps to protect the chuck from potential splashes.

Installation in the Laboratory
1. Thestirrermustbesecurelyxedtoastablesupport-e.g.clampedtoanoriginal
Caframo stand that is on a stable, level surface. See safety instructions on page
3.
CAUTION:
   Thisisnotanexplosion-proofstirrer.Donotuse
 withhighlyammableorexplosivematerials.
WARNING:
Be sure that the unit’s voltage is the same as the
supplied voltage. Information on the unit’s voltage
and current are located on the serial plate.
This unit must always be connected to a grounded
electrical outlet.
2. Chuck removal and attachment:
Loosen the set screw with the allen key found on the chuck key. Remove chuck.
To attach align the set screw with the pilot hole on the shaft. Tighten the set
screw with the allen key found on the chuck key. Make sure that the set screw
isrmlytightened.Openthechuckfullytoprepareforimpellerattachment.
3. Impeller attachment:
Insert the impeller shaft (see accessories) into the open chuck and adjust the
impellertoamaximumlengthof25cm(10inches)[ofa40cm(16inch)shaft]
to reduce vibration. The hollow shaft allows the impeller shaft to come through
the top of the stirrer if necessary. Tighten the chuck’s outer ring by hand and
then secure with the chuck key. Install the chuck guard over the chuck.
Environmental Operating Conditions
All BDC stirrers must operate in the following conditions:
Indoors
1. Altitudes below 2000 meters.
2. Temperatures from 5 °C to 40 °C
 3. Maximum relative humidity 80% for temperatures up to 31 °C decreasing
linearly to 50% relative humidity at 40 °C.
 4. Mainssupplyasindicatedunderthetechnicalspecications.
5. Pollution degree 2 in accordance with IEC 664
“Normally only non conductive pollution occurs.
Occasionally, however, temporary conductivity caused by
 condensationmustbeexpected”
